Xóa lề/lề trái trong ExpanderView

Question

Mặc định triển khai ExpanderView trong ứng dụng mà giao diện người dùng hiển thị và điều khiển expanderView có lề trái này áp dụng cho nó, một số loại thụt đầu dòng. Nó khá ngu ngốc thực sự rằng nó là như thế theo mặc định.

Có cách nào để thoát khỏi lề đó và chỉ cần điều khiển trôi hoàn toàn về bên trái?

Ngoài ra, cách thêm một số văn bản vào hình chữ nhật mở rộng? Không có tài sản như vậy.

Answer 1

Bạn chỉ cần chỉnh sửa Mẫu điều khiển cho Expander. Nếu bạn có Expression Blend nó làm cho nó nhanh chóng và dễ dàng. Bạn chỉ cần nhấp chuột phải vào Expander của bạn trên bản vẽ, chọn "Chỉnh sửa mẫu" và sau đó chọn chỉnh sửa bản hiện tại hoặc bản sao bạn có thể tạo và có thể đặt trong từ điển tài nguyên riêng. Đây là một ví dụ mẫu. Lưu ý 11,0,0,0 Margin trên các mụcCanvas về phía dưới cùng? Bạn có thể sử dụng phương pháp tương tự này để chỉnh sửa chỉ là về bất kỳ mẫu điều khiển nào. :)

Đã muộn nhưng có thể nó sẽ giúp ai đó. Tôi loại bỏ lề đó theo kiểu này. Tôi đã xóa các cột từ lưới mặc định. Hơn nữa tôi tạo ra nó như bảng điều khiển Wrap. Nó có thể được sửa đổi trong ItemsPanelTemplate.
